I will, as I'm curious myself. (and before/after pics are nice to see if all the work was effective) Nop, just slim, long hands and fingers. (according to a piano teacher perfect hands for the piano) That wouldn't surprise me, in the EU we are a lot stricter in which chemicals we allow in the environment or food. (No clue on how sugar replacements got let in though...) I'll just start scrubbing as soon as the Slim is in.
But you do have bathrooms, and they need to be cleaned. You must have something similar that cleans hard water deposits and soap scum, and disinfects.
We use just an all/multi-purpose cleaner. No clue if it removes hard water deposits, it's pretty soft here. (not a lot of chalk in it)
